WEBVTT 00:01.080 --> 00:04.320 I will come back here in this Kali Linux. 00:04.760 --> 00:09.400 Uh, let's go first learn something about this Kali Linux. 00:09.440 --> 00:10.240 Okay. 00:10.280 --> 00:13.000 Some command, okay, that we are going to use through the course. 00:13.000 --> 00:14.520 And very common. 00:14.560 --> 00:18.000 These are very common that we are going to use it a lot. 00:18.040 --> 00:20.160 So you need to learn them okay. 00:20.200 --> 00:24.920 First I have to tell you that in Kali Linux we have to kind of user okay. 00:25.000 --> 00:28.880 Right now we have a normal user and we have used super user. 00:28.920 --> 00:36.720 A normal user is only able to read some file, edit some of the file, but not all the files that the 00:36.720 --> 00:45.640 super user is able to edit, delete and do everything with the system. 00:45.680 --> 00:49.440 So right now I am a normal user. 00:49.440 --> 00:54.040 If I want to be a super user in windows we call it administrator. 00:54.400 --> 00:59.480 I use this command okay, sudo is you and then hit enter right here. 00:59.640 --> 01:04.530 Maybe it will ask for a password if it asks. 01:04.530 --> 01:05.650 So you write curly. 01:05.690 --> 01:06.130 Okay. 01:06.170 --> 01:09.610 That is the password for this curly mission right now. 01:10.570 --> 01:12.970 And right now you see that I am root. 01:13.010 --> 01:14.530 That means I am the super user. 01:14.570 --> 01:15.050 Okay. 01:15.090 --> 01:17.370 If I want to exit, I use exit command. 01:17.410 --> 01:20.250 Now, if I use clear, so it will clear the terminal. 01:20.890 --> 01:25.410 So there is another command that we're going to use that is called PWD. 01:26.170 --> 01:32.810 PWD is a command that shows the current directory you will location right now where you located in which 01:32.810 --> 01:33.690 directory. 01:33.730 --> 01:35.050 It will show you that. 01:35.170 --> 01:38.770 So right now you see I am located in home then Cali. 01:38.810 --> 01:41.930 And if I use PWD so it shows me this one. 01:42.250 --> 01:44.530 And there is another command called Ellis. 01:44.570 --> 01:49.410 Ellis stands for for list I think okay. 01:49.450 --> 01:55.410 And if you use it, it will list all the directory that is located where you look at it okay. 01:56.010 --> 02:01.530 So in your location and you can use some other places. 02:01.970 --> 02:09.430 And for example you look at it in home directory and you want to see what is inside the document again, 02:09.430 --> 02:14.470 you can use it very easily like this list form. 02:16.350 --> 02:19.470 And you see we are inside whom we have colleague. 02:19.750 --> 02:24.070 And if I use poly and then for example. 02:26.550 --> 02:28.350 And desktop okay. 02:28.750 --> 02:29.510 And hit enter. 02:29.510 --> 02:33.310 You see we have nothing on desktop right now okay. 02:33.350 --> 02:35.070 So it is how we can use list. 02:35.910 --> 02:38.470 There is another command that is called CD. 02:38.710 --> 02:41.150 CD stands for change directory okay. 02:41.230 --> 02:43.910 For example I'm trying to go to document folder okay. 02:43.950 --> 02:49.270 So I use CD document and hit enter list. 02:49.270 --> 02:50.110 Here is nothing. 02:50.110 --> 02:51.190 You see my location. 02:51.190 --> 02:52.550 It is document. 02:52.550 --> 02:59.470 If I use PWD which is showing my location right now current location it is into document folder if I 02:59.470 --> 03:00.110 go back. 03:00.270 --> 03:03.590 So I use city and then two dot okay. 03:03.630 --> 03:05.910 And now I am back where I was. 03:06.990 --> 03:11.680 There is one another command which is very, very important. 03:11.760 --> 03:13.080 That is called man. 03:13.120 --> 03:13.480 Okay. 03:13.800 --> 03:14.880 This man. 03:14.920 --> 03:20.600 This man command will show you all information about other command that you want. 03:20.640 --> 03:27.480 For example, I want to use, uh, okay, a list that is here I'm going to see all information about 03:27.560 --> 03:27.880 list. 03:27.880 --> 03:29.320 I don't know how to use it for example. 03:29.320 --> 03:33.960 So I use man list and then it will give me information that I. 03:33.960 --> 03:40.240 How can I use you see here we first use list and then add an option here. 03:40.240 --> 03:44.840 And then name of the file or location of the file. 03:44.880 --> 03:48.120 You see we can use a or all it is. 03:48.160 --> 03:56.080 It says do not ignore enter starting with A or B plus size. 03:56.120 --> 04:07.360 See we have if g, g, h see and a lot of thing here we have L here use a long listing format okay. 04:08.360 --> 04:10.200 And okay. 04:10.240 --> 04:13.120 Here is a lot of thing that you can read if you need it okay. 04:13.120 --> 04:13.180 again. 04:13.220 --> 04:17.500 And if you're somewhere okay about some command so you can use it. 04:17.500 --> 04:19.820 So now I hit Q and then it quit that. 04:20.620 --> 04:20.860 So. 04:23.140 --> 04:24.300 It was it okay. 04:24.340 --> 04:32.900 And also another important information is how we can install something like some application into Kali 04:32.900 --> 04:33.380 Linux. 04:34.140 --> 04:37.260 And we can use apt app. 04:37.980 --> 04:43.620 It then install name of the application like Terminator. 04:43.660 --> 04:46.700 Terminator is not an application right now okay. 04:47.260 --> 04:51.140 Now if I hit enter it must install it again. 04:51.500 --> 04:55.620 But right now you see that it is telling me that permission denied. 04:55.660 --> 05:01.340 That is because I'm not the superuser and I am not allowed to install any application to the Linux. 05:01.380 --> 05:03.860 Okay, so I have to be superuser. 05:03.860 --> 05:05.380 How can I be superuser? 05:05.380 --> 05:13.100 So I use sudo and then this command or sudo is you hit enter. 05:13.140 --> 05:23.950 Now I use apt get It install, for example, update or terminator or let's say a apt get update. 05:23.950 --> 05:25.110 I want to update this. 05:25.110 --> 05:25.510 Okay. 05:26.310 --> 05:28.950 So now it will start updating this okay. 05:28.990 --> 05:35.870 So you need to have network connection while you're updating and while you're installing some application 05:35.870 --> 05:36.990 or something in it. 05:36.990 --> 05:37.390 Okay. 05:37.950 --> 05:42.950 So it was how you can use some basic command okay. 05:42.950 --> 05:49.790 And if you're trying to follow the Linux course and it is not going to be a Linux course, okay. 05:49.790 --> 05:50.750 It is a Python course. 05:50.750 --> 05:57.910 So we are going to learn this simple steps simple commands because we need it okay. 05:57.950 --> 06:08.270 And maybe in the future the full package for Linux Kali Linux penetration testing with Linux will come. 06:08.510 --> 06:10.310 I will record it okay. 06:11.110 --> 06:13.230 And if not so it's okay. 06:13.670 --> 06:17.470 Right now it is enough and we will learn a lot of things through the course. 06:17.470 --> 06:19.270 And let's go for the next lecture.
